2. Change the default boot source (for advanced users)
Entering “2” in the top-level menu provides the option to set the boot source
permanently.
The same boot source options are provided as with the one-off selection, but this time
every restart of the switch will result in the unit booting from the selected source.
3. Update Bootloader
This option allows for the bootloader code to be updated. It is not detailed here, as it is
envisioned that this would rarely need to be done, and only at the request of (and with
support from) Allied Telesis engineering.
